Water Purification,
chemical-free
Smarterial deploys LG Sonic across France, the world-leading ultrasonic technology for algae and cyanobacteria control in industrial water bodies, ponds and reservoirs.
The sector challenge
Cyanobacteria: an economic and health threat
EU Drinking Water Directive
The revised EU Drinking Water Directive strengthens microbiological monitoring requirements and cyanobacteria control. Reservoir and water body managers must adapt their treatment systems to meet new compliance standards.
Sanitary closures and direct revenue losses
A single sanitary closure event translates into direct revenue loss. At Val Joly (France), the ban on nautical activities in July 2025 struck at the peak of the summer season.
Chemical treatments falling short
Traditional chemical treatments are costly, polluting, and ineffective against heavy algal blooms. Site managers need a proven, scalable and regulatory-compliant alternative.
The solution
LG Sonic uses specific ultrasonic frequencies to inhibit the growth of algae and cyanobacteria — without chemicals, without impacting aquatic wildlife. The MPC-Buoy system integrates real-time AI monitoring that continuously adapts frequencies to the conditions of the water body.

Ultrasonic technology in action
Algae migrate to the surface for photosynthesis and to the bottom for nutrients. Water turns green and toxic, risk of site closure.
Ultrasonic waves target algae gas vacuoles. Deprived of light and nutrients, they sink and die without releasing toxins — water clarified within weeks.
What we observe, from the field
Day 14 post-deployment. The water has lost its green tint. The site manager calls: "This is the first time in six years we haven't had to close in the middle of August." He hadn't planned to tell his team until he was certain.
Nautical leisure · Closure avoidedThe technical director's first question: "And if it doesn't work?" We turned it back: how much does a sanitary closure cost you per year? Silence. Then: "Let's keep talking."
Cooling basin · Qualification phase60 countries. 10,000 units deployed. France remains structurally under-equipped compared to Germany and the Netherlands. That gap is our starting point — and the reason we decided to focus here.
